  -----------
  [RFC][Docs][Clang][AMDGPU] Add AMDGPU builtins documentation

Add comprehensive documentation for AMDGPU target-specific builtins
(`AMDGPUBuiltins.rst`) covering argument semantics, restrictions, and
lowering notes for all builtin families.

This documentation was generated by AI (Claude) by cross-referencing:
- `clang/include/clang/Basic/BuiltinsAMDGPU.td` (builtin definitions)
- `llvm/include/llvm/IR/IntrinsicsAMDGPU.td` (intrinsic definitions)
- `clang/lib/Sema/SemaAMDGPU.cpp` (argument validation/constraints)
- `clang/lib/CodeGen/TargetBuiltins/AMDGPU.cpp` (lowering logic)

I did my best to proofread the parts I'm familiar with, but it would be greatly
appreciated if more people could help review it as well.
